RTC-lib for Windows…

Thanks to the help of Thomas Grill and Peter Elsea most of the externals of my "Realtime Composition Library" (RTC-lib) has been ported to Windows XP. Furthermore, I transformed some Mac externals (divmod, sequence, trans-lin and trans-log) into abstractions.

It looks as if a Windows version of the RTC-lib is more or less ready for take-off. There is one point: as I am not working on a PC I cannot supply any support or answer Windows specific questions. Please refrain from sending me emails about those topics.
